This invention relates to so-called stapling or tacking machinesoperated by hand, such as are adapted for setting staples througharticles for securing them together or for 50 as including othermachines attaching labels and thellike to shipping boxes, etc. and hasfor "an object to provide an improved means .to assist inthe easy andtireless operation of. these machines, .and more especially relates tothe provision of a handle or rip adj acentthe plunger operating knob o?the machine to be gripped by the fingers while the base of the palm ofthe hand rests on the top of the plunger operating knob to facilitateeasy and tireless operation of the machine.

-With the foregoing and other objects in View, the invention consists incertain novel features of construction, combinations and arrangementofparts as will bemore fully disclosed in connection with theaccompanying drawings, it being understood any changes and modificationsmay be made in the structures disclosed without departing from theprinciples of the invention. In these drawings j:

Fig. 1 is a side elevation of a tacking machine showing one form ofmyimprovement applied thereto. Y l Fig. 2 is atop plan View thereof; r'Fig. 3 is .a side elevation showing amodi fied construction. I

. Fig. 4 is a topplan view thereof. I

Figs; 5 and6 are a sideelevation and top '5 plan view respectively orstill another modified construction, an 7 Figs. 7 and Sare a sideelevation and top plan viewrespectively of a further modifiedconstruction.

In the drawings, I haveshown improved construction as applied to aso-called tacking machine such as is used for securing tags and labelsto shipping boxesand the like, but'this improvement is not limitedto usewith this particular type of machine, but

of course, may be used with so-call-ed stapling machines orothermachines. similarly operated, and in the. specification and claims I usethe term tacking machine in a broad sense operated in a similar manner.

.Referring to Figs. 1 and :2, the machineillustrated comprises a housing10, carrying at its front or forward end a reciprocable plunger 11guided. in suitable guideways in the housing, and normally held in itsupper or retracted position by a springlQ, the plunger being depressedfor driving or settingthe staples bymeans of a hand knob '13 secured'totheupper end thereof. The house my present invention. The usual' guidebar for the staples "is shown projecting some what atl, and the housinghas the usual base 15 to rest on the article being tacked during. thetacking. operation. These ma: chines are usually operated by pressing onthe top of the knob or hitting it :a blow with the hand, but if operatedcontinuously this is apt to make the handsore, and in the case .of acommon type tacking Ina-chine requires the use of both hands foroperating the machine.

one to holdthe machine in. position and the V otherto operate the knob.,With this im proved construction thetacking machine may be operatedwith'one hand so thatfthe other hand may be free to hold the label, andit also makes the operation of the machine easier and less tiring.

Theform shown in Figs. 1 and 2 comprises'a handle member 16 shapedsomewhat as a sort. of bracket secured to thehousing, in

the presentfcaseit being secured to the housing by attaching ittov oneside ofthe'guide bar 14 by any suitable means such as the screws'17. Bythis arrangement, it does not interfere with the insertionof the staplesinto the housing. .This handle member extends upwardly and forwardlyfrom adjacent. the

rear end ofthe housing toward thehand knob 13 where it includes a fingergrip 18. I

This grip-inay be a-n integral part of the handle member as indicated inthe modlfied constructions of Figs. 3 to 8, but in the form shown inFigs. 1 and 2, it is a separate member pivoted to the supporting part ofthe handle member at 19 so that it'may be used as indicated in fulllinesas extending in the plane of the housing and thus provides theordinary handle used'with thesetacking ma chines to be held in one handwhile the knob is being operated by the other hand, or in transportationand storage so'that itcanbe more easily packed. and requires.less'ispace; or it may be turnedto a transverse position as indicatedin dotted lines. That is, to a position substantially transverse theplane of the housing so that it may he gripped by the fingers 20 of thehand as indicated dotted lines, Fig. 1, while the base ofthe palm of thehand 21 rests on the top of the knob 13. It willbeevidentthat' in thisarrangement the hand forms a sort of lever with the finger grip 18 asthe pivot or fulcrun topermit easy operationof the plunger 11 merelyforcing the palm of the hand downwardly. It has been found thatthis.makesfor very easy operation of the machine and is much less tiringon the operator. Italso permits the useof this tacking machine with'onehand leaving the otherhand free'for holding the label. This constructionand arrangement permits easy carrying and shifting of the device andplacing and holding it in any position desired. The finger grip 18'maybe turned downwardly atits opposite ends as shown at 22 to improvethe appearance and also prevent the fingers slipping off. This maybeused as a two hand machine by gripping the handle member andholding'themachine in position with one hand while operating the plunger with the.other hand, the bar'18 being in either position desired;

l In the form shown in Figs. 3and 4, the effeet is practically the sameas far as furnishing a grip for the fingers and a sort'of fulcrum orleverage for the hand in operating the plunger is cOncernedQbut'thehandle is constructed somewhat differently. Thehan dle member indicatedat 23is secured to the 1 111 housingthrough the stapling guide bar byany suitable means such as the screws '24, but

7 may, if desired,first extend somewhat rearwardly as indicated at 25and then u'pwardly and forwardly toward the hand knob, and is shaped toform an intermediate grip 26. ,At its forward end it is loopedtoformfthe finger grip '27- adjacent the knob '13 and extendingtransversely the plane of the. housing, the same asthe cross member 18,-in the :dotted lineposition of-Figs. 1 and 2. In this form, thedeviceismlanipulated and operated the same as in thefirst form, andalthough-in the first form the device may beheld by one hand whilegripping the-handle member 16 while the knobisbeing operated with theother hand, in the form shown in Figs. 3 and ft, the

handle member, this is shown at 29 as an integral part of the handle"member extendlng transversely .thepl'ane of the housing. It may be givenany desirable shape to more comfortably fit the fingers.

Inthe form shownin Figs. 7 and 8, the

finger grip 30, extending transversely the plane of the housing, ispractically the same as that shown in Figs. 5 and 6, but the handlemember instead of being secured adjacent the rear end of the housing isin this case securediadjacent the forward end thereof. It

may comprise a brac k'et member 31 straddling the housing and'securedthereto by any suitable means such as the bolt or screw 32, and

is integrally connected'with thefinger grip 30 by connecting portion 33.The operation 'of all of these types is the same. That is, thetransversely extending finger grip is located adjacent the plungeroperating knob, and they all may be operated as shown in dotted lines inFig. 1 by passing the fingers around andunder the finger grip andresting the base of'the palm of the hand on topof the plunger knob. Inall forms the handle member may be detached'from the housing by merelyremoving the securing screws. j

I I-Iavingthus set forth the nature of my invention, what I claim is: I

V 1. Ina tacking machine or the like, a housing, a" movable plungerhaving a knob for hand operation thereof, and a handle secured to thehousing and extending to a position adj a'cent said knob and includinga. finger grip adjacent said 'knob pivoted so'that it may occupy aposition transversely the plane of V the housing and may also be swungto a position in substantially the plane of the hous- 2.. In a tackingmachine, a housing, a movable plunger atvthe forward end of saidhousing',"a knob on said plungerfor handuoperation thereof, and a handlesecured to the housing adjacent the opposite end thereof andextendingupwardly and forwardly over the housing to a position adjacent the knob,said handle having a finger grip adjacent said knob'pivot'ed so that itmay occupy a positiontransversely'the plane of the housing and may alsobe shifted to a position in the plane of the remainder of the handle.

' 3, In a tacking machine, a housing, a movableplunger at the forwardend of saidhousing, a knob'on said plunger for hand operation thereof,and a handle secured to the housing adjacent the J opposite end thereofand extending upwardly and forwardly over the housing to a positionadjacent and spaced from the knob, said handle having portions forming afinger grip adjacent said knob extending transversely of the plane ofthe housing for engagement of the fingers while 7 the base of the handrests on the knob for operating it, permitting either two or one handoperation of the machine.

In testimony whereof I aflix my signature.
